Destiny 2 Season of the Haunted Week 6: Caiatl Confronts Ghaul's Nightmare
Destiny 2 Bound in Sorrow Week 6 guide: beat the Sever-Resolve mission, shoot the fuse, open Immolation Hall, and defeat Ghaul's Nightmare.
Destiny 2's Season of the Haunted ended long before 2026, but its Week 6 Bound in Sorrow chapter still stands out as a compact example of how Bungie tied seasonal mechanics to character-driven storytelling. During that week, the focus shifted to Empress Caiatl and the Nightmare of Dominus Ghaul. The story did not simply repeat the self-reflection arcs of Crow and Zavala. It pushed Caiatl to accept help after a solo failure, then asked Guardians to complete a Severance Ritual with her in the Underbelly of the Leviathan. The result was a mission that combined navigation, fuse-shooting, arena control, and a final confrontation with Ghaul's Nightmare.
The season opened with the Leviathan's return, now infested by Nightmares. Eris Morn, Commander Zavala, and Crow performed a Binding Ritual that attached personal Nightmares to the two Guardians. The hope was that pacifying those entities would help the group sever Calus's new connection to the Pyramid. Crow faced his past identity in the first two parts. Zavala confronted Safiyah in weeks three and four. By week five, Caiatl had been revealed as the next target: the Nightmare of Dominus Ghaul haunted her, and she tried to defeat it alone. She failed. In Week 6, she returned with new resolve and accepted Eris's Hive magic and the Guardian's support.
To begin, players spoke to Eris at the HELM and earned another Bound Presence by completing a tier-three Nightmare Containment activity. That step kept the seasonal loop intact: ritual hub, activity, then story mission. After that, Guardians joined Caiatl and descended into the Leviathan's Underbelly. The mission, Sever-Resolve, reused the previous week's location but changed the route. The first electrical barrier was already disabled; the second was active again. That small change forced players to re-read the space instead of sprinting through it.
| Step | Action | Key detail |
|---|---|---|
| 1 | Speak to Eris at the HELM | Start the Week 6 Bound in Sorrow step |
| 2 | Complete tier-three Nightmare Containment | Earn another Bound Presence |
| 3 | Join Caiatl in the Underbelly | Begin Sever-Resolve |
| 4 | Clear the approach | First barrier is down, second is active |
| 5 | Shoot the fuse | After speaking to Caiatl, drop down and turn right |
| 6 | Open Immolation Hall | Use the right-hand hallway further down |
| 7 | Lure the Unrelenting Nightmare | Ignite the hall quickly to destroy the enemy |
| 8 | Fight Ghaul's Nightmare | Finish the Severance Ritual |
The fuse sequence was the main mechanical gate. After speaking to Caiatl, Guardians dropped down and turned right into the nearest doorway. Immediately to the right was an electrical fuse that had to be shot. Further down, another hallway on the right unsealed the Immolation Hall. The room demanded crowd control and timing. Guardians needed the Unrelenting Nightmare to follow them into the area, then ignite the hall quickly to destroy the enemy. It was a short puzzle, but it punished players who rushed ahead without checking whether the Nightmare had followed.
The final fight against the Nightmare of Dominus Ghaul closed the third Severance Ritual. In narrative terms, the battle mattered more than the loot. Caiatl did not erase her history or pretend that Ghaul's shadow was harmless. She confronted it with allies at her side. That beat contrasted with her earlier attempt to solve the problem alone, and it gave the season one of its clearer character arcs. The mission also reinforced the season's central idea: Nightmares are not defeated by ignoring them, but by binding them, understanding them, and then severing their hold.
After Sever-Resolve, Guardians returned to the HELM and listened to a private transmission from Caiatl. She thanked them for their help. Eris then asked to speak at the Crown of Sorrows about the third Severance Ritual. Her dialogue pointed to a missing link in the plan to stop Calus. Even with Ghaul's Nightmare resolved, the larger threat remained. Calus's connection to the Pyramid and the Witness was still not fully explained, and the season had one final story segment left to deliver.
As of 2026, Season of the Haunted is a retrospective chapter rather than a live seasonal event. The original platform list included PC, PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and Google Stadia. Stadia has since shut down, so modern players should treat that part of the old listing as historical. The Week 6 structure, however, remains useful for understanding how Destiny 2 used a single mission to close a character beat while keeping the seasonal mystery alive. 😈🔮
According to coverage from TrueAchievements, Destiny 2 mission design is often remembered not just for combat encounters but for how objectives, triumphs, and player progression reinforce narrative beats, which fits Week 6 of Season of the Haunted as Caiatl’s Sever-Resolve mission used simple traversal and encounter mechanics to give emotional weight to her confrontation with Ghaul’s Nightmare.
